Claims.

The invention relates generally to illuminated charts, and primarilyseeks to provide a novel form of chart for recording and displayingattendance at places of assemblage such as clubs,

5 churches, schools, lodges and the like.

In its more detailed nature the invention resides in the provision of ahollow box-like frame containing a source of light and a rear doorthrough which access may be had to the interior of the frame, the frontface of the frame coinprising a panel displaying a column of names, rowsof sight apertures beside the respective names and corresponding to theallotted or possible number of attendance, and novel means whereby onlyselected apertures or groups of apertures may be made to display lightindicating attendance of the particular individuals or similarrecordings.

Another object of the invention is to provide a novel record and displaychart comprising an apertured face panel, an opaque backing panel havingweakened and readily removable portions underlying and covering saidapertures, and an intermediate sheet of transparent or translucentmaterial, preferably distinctly colored, whereby selected weakenedportions may be removed to cause light to be admitted through associatedapertures and the light admitting covering there behind thus simulatinga light indicative of an 30 attendance or like record.

Other objects will in part be obvious and in part be pointed outhereinafter.

To the attainment of the aforesaid objects and ends, the invention stillfurther resides in the novel details of construction, combination andarrangement of parts, all of which will be first fully described in thefollowing detailed description, and then be particularly pointed out inthe appended claims, reference being had to the accompanying drawings,in which:-

Figure l is a face View of my improved chart.

Figure 2 is an enlarged detail face View of a portion of the chart.

Figure 3 is a rear elevation of a portion of the face panel, parts beingbroken away.

Figure 4 is a horizontal cross section taken on the line 4 4 on Figure1.

In the drawings in which like numerals of reference indicate like partsin all of the figures 5 50 designates an open rectangular frame which isclosed at the rear by a cover plate or wall i3. In the back wall of theframe is provided a door l' through which access may be had into theinterior of the chart frame.

The front of the frame is covered by a com- 1935, Serial No. 34,347

(Cl. ll0---133) posite panel suitably trimmed by molding il to display ahead portion 9 which may be marked to indicate the parti-cular use towhich the chart is put as indicated in Figure 1, a name column illassuming that the chart is to be used as an attendance record as hereindisclosed, and a main record and display body ii.

In the column l0 a plurality of grooved plates E2 are aihxed to thepanel for the purpose oi removably receiving plates embodying the namesof the individuals whose attendance it is desired to record and display.

The composite front panel comprises a iront sheet i3 of masonite or anyother suitable sheet material, an opaque backing sheet iii, and anintermediate sheet I 5 of transparent or translucent material,preferably colored gelatin sheeting, crepe paper or the like. The frontsheet i3, within the body portion i i thereof, is equipped withsymmetrically disposed horizontal rows of sight apertures i6. If thechart is to be used to record and display weekly attendance throughoutthe period of a year 52 such apertures will be disposed beside each ofthe name plates in the column l0. When used in this manner the number ofapertures uncovered in each row, and thereby emitting light, willindicate the number of timesl and on which Sundays the person attendedclass.

The opaque backing sheet l!! includes a weakened circular portion ilunderlying each 0f the apertures I6 which portions may be formed bypunching through a part only of the area underlying the sight apertures,as illustrated in Figures 2 and 3 of the drawings.

A light source I8 is mounted within the chart framing and it will beobvious that so long as the backing sheet I4 remains intact no lightwill be admitted through the intermediate sheet l5 and the apertures I6which it underlies. It will be equally obvious, however, that when oneor more of the weakened portions il of the backing sheet are removed,light from within the interior of the chart framing will be displayedthrough the intermediate sheet i5 and the respective aperture orapertures I6 thus exposed, and each display of light will record andindicate an attendance of the individual beside whose name the displayoccurs. This display of light simulates the lighting of a lamp toindicate each attendance and may take the form of a white light when anordinary transparent intermediate sheet !5 is employed, or any desiredcolor light depending upon theform and color of intermediate sheetemployed. Access may be had to the interior of the chart through thedoor 1 for the purpose of tearing out the weakened portions I1.

It will be observed that the weakened portions Il are considerablylarger than the apertures I6 which they underlie. By this means, whenthe weakened portions are torn out, the ragged edges I9 resulting fromthe tearing away cannot be seen through the apertures I6 and thus theclear and well defined circular light display desired is assured.

It will be obvious that my improved chart may be employed for recordingand displaying various records other than the attendance record referredto and disclosed herein and this modification of the invention and theuse of various forms and colors of intermediate sheets and temporaryaperture covering areas is contemplated and embraced within the scope ofthe appended claims.

I claim:

1. A record and display chart including a composite panel comprising anapertured sheet the apertures in which designate possible record units,a second sheet having weakened areas covering the front sheet aperturesand removable to admit light through selected apertures to record anddisplay record unit designations, and a third sheet of light admittingand modifying material covering the apertures and eiective upon removalof said weakened portions to modify light passing through saidapertures.

2. A record and display chart including a cornposite panel comprising anapertured sheet the apertures in which designate possible record units,and a second sheet having weakened areas covering the front sheetapertures and removable to admit light through selected apertures torecord and dispose record unit designations, said weakened portionsbeing larger in area than the apertures whereby rough edges of thebacking sheet occasioned by removal of the weakened portions will notshow through the apertures.

3. A record and display chart including a composite panel comprising anapertured sheet the apertures in which designate possible record units,a second sheet having weakened areas covering the front sheet aperturesand removable to admit light through selected apertures to record anddisplay record unit designations and a third sheet of coloredtranslucent material covering the apertures and eiective upon removal ofsaid weakened portions to modify light passing through said apertures.

4. A record and display chart comprising a box-like frame; a source oflight in the frame; a front closure panel in the frame including anapertured front sheet the apertures in which designate possible recordunits, a backing sheet having weakened areas underlying the aperturesand removable to admit light through selected apertures to record anddisplay record unit designations, and a transparent sheet disposedbetween said front and backing sheets and effective upon removal of saidweakened portions to modily light passing through said apertures.

5. A record and display chart comprising a box-like frame; a source oflight in the frame; a front closure panel in the frame including anapertured front sheet the apertures in which designate possible recordunits, a backing sheet having weakened areas underlying the aperturesand removable to admit light through selected apertures to record anddisplay record unit designations, and a colored translucent sheetdisposed between said front and backing sheets and eiective upon removalof said weakened portions to modify light passing through saidapertures, said weakened portions being larger in area than theapertures whereby rough edges of the backing sheet occasioned by removalof the weakened portions will not show through the apertures.
